How to know your ideal contracted power

Why we should look at it

He Power term It is the concept we call "fixed" on our electricity bill. This is what we pay every month or every two months, as we are billed, for having the kW of power we have contracted. It is calculated like this:

kW of contracted power X billed days X power price of that period (the one that your company applies to you).

Until the prices change, the result we get will be the same every month, but we can reduce it, adjusting the power section to our needs. Right now this is one of the most effective saving measures, since on February 1, 2014 the power price rose Approximately 18% in all companies and all rates and in August it had already more than doubled.

It can be a saving small if we go down one or two sections of power or something more “serious” if this descent implies a change of access rate to a lower one, since in the latter case, in addition to multiplying by a smaller number, you will do the operation with a lower price. If you have between 0 and 10 kW your access rate will be 2.0A, between 10 and 15 kW the 2.1A and if they are more than 15 kW we will talk about 3.0A.

To give you an idea, right now, for every kW reduced (between sections and sections there may be more than 1 kW) you would save about 60 euros per year on your bill For example, if you have 4.6 kW and you go down to 3.45 kW you would be reducing 1.15 kW, with which the approximate annual savings would be about 65 ¤.

Ideal power (approximate) according to each case

If we already have light we can ask ourselves reduce the contracted power and if what we want is to register the supply we will have to know which one are we going to hire.
The power we need will depend on two factors. On one side of type and quantity of electrical appliances we have and the power they need.
On the other hand, it will also depend on how do we use them. Do you need to connect all the devices at the same time? Or can you distribute them in time?

Although this seems a bit abstract we have more or less exact methods that can serve as guidance. To start you can take a look at this table:

Power sections currently standardized

As you have seen, it is not possible to choose a random power, but rather we must opt ​​for a section between the currently standardized. These sections are divided between those of single-phase installations (the most common) and those of three-phase installations, which divide the power into three phases. At the end of this article you have the “old” sections most used in homes and their current correspondences, in addition to other useful details related to the contracted power.

If in spite of these indications you have doubts about a possible reduction in power or which to hire if you must register a supply, contact your marketer, they will know how to guide you.
